So, there are two access points with the ESSID “MySQL-Hyatt” that I can see from my coffee drinking spot here in the foyer. iwlist tells me that they have encryption off, which matches what the conference handbook says should be the case. No DHCP leases are being offered though. I guess that means that the conference network hasn’t been commissioned yet. Oh well.
Update: Oh, it works in the conference rooms, which have a different ESSID.
